HlsDuplicateBandwidth

Duplicate Bandwidth in Variant Streams

Event
It triggers if the Master playlist or manifest has two similar Bandwidth values for different Variant Streams within the same codec.
The Bandwidth parameter is the upper bound of the overall bitrate for each segment, in bps. It includes any container overhead that appears or will appear in the playlist.

OttBandwidthMissed

Bandwidth Missed in Variant Stream

State
It triggers if the Bandwidth field is not present in the Variant Stream description of the Master playlist or manifest.
In the Player analysis mode, the probe will not switch to Variant Streams with the Bandwidth field not specified. If there is no bitrate information for all Variant Streams, the probe analyzes an arbitrary Variant Stream without switching to other Variant Streams.

  • The segment size (content-length) is equal to 0 bytes;

  • Average segment bitrate exceeds the bandwidth (stated in a Master playlist) by 10 times. Average segment bitrate is calculated as the file size (content-length) divided by declared segment duration. Additionally, if the segment size is more than 15 MB, the download of this segment is terminated.

HlsSequenceNumberDiscontinuity

Segment Loss

Event
It triggers if one or several Media playlists (#EXT-X-MEDIA-SEQUENCE discontinuity) along with segments are missing during analysis. For HLS only.
There are several causes of the error:

  • Segment download bitrate is too low that results in skipping download of subsequent playlists;

  • Playlists are not available for downloading (Manifest Download Failure triggers additionally);

  • Issues with content generation at the headend: broken numerical sequence of playlists, restarts or pauses in transcoders/serializers operation. Note, if skipped playlists do not result in segments loss, the error does not trigger.

HlsStaticManifest

Static Manifest Error

State
It triggers when the probe downloads the same playlist during the specified number of attempts. If the probe detects the static playlist which has the same content during two sequent downloads, the download interval will be reduced to the half of the segment duration OR to the half of the TARGETDURATION tag value (the lowest value is selected). The error and reduced download interval will persist until the probe downloads an updated Media playlist. For DASH: only those MPD files can be validated in which Segment List information is specified in the SegmentList or SegmentTimeline element.
Set the number of download attempts in the Attempts of identical playlist downloads field in the Threshold tab.

HlsManifestError

Manifest Error

Event
Depending on an OTT type, it triggers if:
HLS

The segment download timeout is equal to double the segment stated duration, but not less than 5 seconds.

HlsStartWithIDR

Start With non-IDR Frame

State
It triggers if a segment starts with a non-IDR frame. Analysis of encrypted segments (decryption keys are not accessible) is unavailable. Enabling of video analysis options in the Add Task form is not required.

Ott_InterlacedVideo

State
It triggers if a segment has interlaced video stream. Analysis of encrypted segments (decryption keys are not accessible) is unavailable. Enabling of video analysis options in the Add Task form is not required.

HlsSkipSegment

OTT Buffer Overflow

Event
It triggers if system low performance results in OTT buffer overflow with downloaded segments that cannot be timely analyzed by a probe. The system starts skipping segments to avoid RAM overflow.

HlsBadSegmentDuration

Bad Segment Duration

Event
It triggers if declared segment duration exceeds or less than the estimated duration by 10 times. Estimated duration is calculated as the segment size (received in a header of http server response) divided by declared bitrate of variant stream (SegmentSize/DeclaredBitrate).

HlsSegmentZeroDuration

Zero Duration Segment

Event
It triggers if zero duration segment with segment size less than 564 bytes (three TS packets) is detected. If the segment duration is not declared, then the size of each downloaded segment is validated. However, if the downloaded segment size (content-length) is equal to zero, then regardless of its duration the Bad Segment Size event triggers.

OttDuplicateRenditionUri

Duplicated URI

Event
It triggers if some Alternative renditions or Variant Streams have the same URI in a Master Playlist or in a manifest.
For HLS only.

HlsMediaPlaylistEvent

Media Playlist Event

Event
It triggers when:

AdInsert_missing

SCTE-35 Ad Insertions Are Missing

State
It triggers when the probe does not detect the start of an Ad insertion (based on SCTE-35 tags data) during the specified period. The state disappears when the probe detects an Ad insertion start. The trigger is implemented on the basis of the SCTE-35 Advertisement Insertion event.

SCTE35Ott_missing

SCTE-35 Tags Are Not Present in the Playlist

State
It triggers when the probe does not detect SCTE-35 tags in a playlist during the specified period. The trigger is implemented on the basis of the SCTE-35 Tag in OTT Playlist event. For subtitles, you can disable SCTE-35 tags monitoring in Thresholds settings.

Video_buffer_overflow

Media Buffer Overflow

Event
It triggers if system low performance results in media buffer overflow and audio/video data cannot be timely analyzed by a probe. The system starts dropping data before decoding. The data is dropped after TR 101 290 analysis and bitrate calculation, thus, the error does not influence the results of stream integrity analysis. This statement is also applicable to OTT, data drop before decoding does not influence calculation of segments download rate and detection of OTT errors.
The Media Buffer Overflow error occurs only if QoE options are enabled in a task (i.e. video decoder or audio decoder is used).

Resumption

Task Crash Detected

Event
It triggers if a child process analyzing the stream has been restarted by the parent process, because no reply was received within 10s. Parent process monitors the tasks (child processes) performance and in case of critical error restarts the tasks with backward recovery.

Stalled

Server Lost Connection to Probe

State
It triggers if the server does not receive data from a probe within 60 seconds. Afterwards, the connection with the probe is considered to be lost.

ServerConnectionLost

Probe Lost Connection to Server

State
It triggers if connection from the probe to server cannot be established within the stated period.

Pcap_loading_error

Pcap Loading Error

State
The Ethernet parameters are measured under the following conditions:
Windows: The Npcap (https://nmap.org/npcap/) packet capture library should be installed on the PC before a probe starts. While installing the library, WinPcap API-compatible Mode and Support Loopback Traffic options should be selected.
Linux: The probe should be launched with root privileges (sudo ./streamMonitor).

Record_access_error

Record Access Error

State
It triggers when the probe cannot access the ‘./record’ folder, its subfolders and content. Usually, the error occurs when the probe was initially started with superuser privileges and then was restarted with regular user permissions. To address the error, stop the probe and change owner/access permissions for the ‘./record’ folder and its content.

5.10.4. Table of Message Identifiers

Information about events, states and alarms may contain the extended data represented as a message ID (see the table below) and returned parameters. This approach allows organizing messages localization.

Message texts may contain macros which should be cut off or replaced. There are two types of macros:

  1. %{PARAMETER_NAME} - a macro with a parameter that should be present with a message. PARAMETER_NAME - a parameter name, a name should contain the following symbols: A-Z, a-z, -, _.

  2. %[OPTIONAL_PARAMETER_NAME: some text with {OPTIONAL_PARAMETER_NAME} inside] - a macro with an optional parameter. It consists of two parts: a parameter name (it meets the same requirements as those for the required parameters) and a text which should be inserted if a parameter is present. If a corresponding parameter is absent, the macro should be cut off. The {OPTIONAL_PARAMETER_NAME} sequence which may be present in a text should be replaced with an optional parameter value.

EXAMPLE:

Macro with a required parameter
"data": {
  "messages": [{
    "id": 502,
    "params": {
      "resolution": "0x0"
    }
  }]
}

Message output result: "Invalid resolution='0x0'"
Macro with an optional parameter
"data": {
  "messages": [{
    "id": 121,
    "params": {
      "descriptor_length": 28
    }
  }]
}

Message output result: "Binary data parsing error: incorrect descriptor_length '28' bytes."
